Thanks Tom,

You have given me a lot to ponder on and start building !!

I'm starting on it and I'll keep you and the community posted on the progress.

Thank you so much Tom.. It's great to connect with like minded people. 1. The idea of hot cap in the burn chamber is fantastic. I will give it a try for sure. 2. Utilising cold draft ? I'll have to get back to the drawing board and see how much of this can be achieved with things as they stand now. ...

.... Are you sure about those temperatures? Even just 400° Celsius is hot enough to melt lead. 800° C would melt aluminum. 1000° C is near the melting point of copper, just to roast vegetables? Yes, these temperature are possible with a rocket oven design . We do not use the direct flame to roast v...

Yes, it's masonary refractory j tube rocket married to a dome oven . The burn chamber cannot be disturbed as any obstruction to the air flow in the burn chamber leads to inefficient burning = more wood required for same amount of output. So retrofitting the hot end in either the burn chamber or the ...

Hi all, I came across this community while I was searching for different ways to use residual heat from my food processing operations. I found the discussions here very useful and exciting. Now coming to the problem to adress - We run a food processing buisiness and have an oven that is built upon a...

How about a Stirling cryocooler / even a refrigerator, driven by a bigger Stirling Engine?

It will be great fun to build one !!
